Shia LaBeouf has been arrested again.

Just over one week after his Feb 17 arrest, the Megalopolis actor was rearrested and charged with an additional misdemeanour count of simple battery on Saturday.

According to The Guardian, the new battery charge is related to his initial arrest during a Mardi Gras celebration, where he was charged with two counts of battery for allegedly striking an unidentified victim multiple times.

LaBeouf's attorney Sarah Chervinsky, said that the 39-year-old actor voluntarily turned himself in at the Orleans Parish jail after learning that a new arrest warrant had been issued.

She said: "No regular person would be required to post over $100,000 (S$127,000) in bonds, and be jailed two separate times for one misdemeanour incident. Just as he does not deserve preferential treatment, LaBeouf also does not deserve to be treated more harshly by the police and courts just because he is a public figure."

He posted a bond of $5,000 and was released from police custody.

During the original Feb 17 incident, LaBeouf was arrested on two counts of misdemeanour battery following an alleged altercation at Royal Street Inn & R Bar during Mardi Gras in New Orleans.
